LIMITING CASES OF A DYNAMIC SYSTEM DESCRIBING THE STATICS OF REACTIVERECTIFICATION OF A BINARY MIXTURE

The behavior of operating lines for the reactive rectification of a bi nary homogeneous mixture is studied using qualitative methods of analy zing dynamic systems. Three limiting cases of the rectification are co nsidered: (1) with a low-rate chemical reaction, (2) with a high-rate chemical reaction, and (3) with a small liquid reflux. Reversible and irreversible first-order chemical reactions for zeotropic and azeotrop ic binary mixtures are studied as examples. It is shown that the opera ting line can intersect the vapor-liquid equilibrium curve no more tha n once.
